in thy book

56:8 in thy book. This is probably a reference to God’s “book of remembrance” (Malachi 3:16).

Psalm 57 (title) Al-taschith. “Al-taschith” means “Destroy not.” It is used in the headings of Psalms 57, 58, 59 and 75. This historical reference in the title is to I Samuel 22:1-5, when David was in the cave of Adullam.
